Which Of The Following Alkene Is Most Stable

Which of the following alkene is most stable

So in general, more substituted alkenes are more stable than less substituted alkenes. So a di-substituted alkene is more stable than a mono-substituted. A tri-substituted is more stable than a di-substituted, and a tetra-substituted is the most stable of them all.

Which of the following is the most stable alkene :- a ch3 ch2 CH ch2 B ch3 CH CH ch3 C ch2 ch2 D ch3 CH ch2?

Option D's alkene has two substituents, while the other two alkenes are conjugated and hence more stable. Now, we can see that of the alkenes in options B and C, B contains an additional alkyl group, making it more alkylated than C, and so B is the most stable alkene. Was this answer helpful?

Which of the following is most stable alkene R2C CR2?

According to Saytzeff rule, highly substituted alkene is most stable. So R2C=CR2 is most stable, as it is highly substituted containing 4 alkyl group at double bonded carbon.

Which alkanes are more stable?

Branched alkane hydrocarbons are thermodynamically more stable than straight-chain linear alkanes. This thermodynamic stability is also manifest in alkane bond separation energies.

What is the stability order of alkenes?

Summary: Stability of Alkenes As C-H bonds are replaced by C-C bonds, the stability of the alkene gradually increases in the order mono (least stable) < di < tri < tetrasubstituted (most stable).

Which is the most stable form?

Complete answer: Graphite is thermodynamically the most stable form of carbon. Its standard enthalpy of formation is thus taken as zero. Let us see why it is more stable than all the other given allotropes of carbon.

Which compound is more stable between CH3 CH CH2 and CH3 CH CH CH3?

Explanation: Greater the number of alkyl groups attached to a positively charged carbon atom, the greater is the hyperconjugation interaction and +I effect of methyl group greater is the stabilisation of the cation. Thus, (CH3)3C+ is more stable than CH3CH2 + and + CH3.

Which of the following is correct order of stability of alkene CH3 CH CH2?

So, we can arrange them in a way that higher the number of hyperconjugation structures, higher the stability of alkene. So, Correct Option is (B) iv > iii > ii > i.

Which of the following is most stable CH3 CH2 CH?

CH3 -- CH (1) -CH2 (3 CH2 =CH-CH2 The most stable carbocation is CH3 (4) CH3. 2° carbocation i.e., CH3CH+CH3 is more stable carbocation than 1° carbocation because 2° carbocation has more hyper conjunction effect i.e it has 6 alpha hydrogen which is more stable.

Which is more stable Mn2+ or CR2+?

ANS: (i) It is because Cr2+ loses electron to become Cr3+ which is more stable due to half filled t2g orbitals, whereas Mn3+ will gain electron to become Mn2+ which is more stable due to half filled Page 2 2 d-orbitals.

Which of the following is the most stable alkene a R2C CR2 B RCH CHR C rch2 ch2r D CH2 CH2?

R2C=CR2, R2C=CHR , R2C=CH2 , RCH=CHR and RCH=CH2.

Which is more stable ti4+ or Cr3+?

This is Expert Verified Answer out of these ions Cr3+ is most stable due to cystal feild spliting concept.

Which is more stable alkane alkene?

Alkanes are more stable because alkenes and alkynes have double and triple bonds trhough the double bonds or the triple bonds: these last use have bond made through orbitals p-greek that are more week than the sigma orbitals.

Which is more stable alkene alkyne?

Alkynes are less stable then alkenes and alkanes despite the bond being stronger. This is not really intuitive, because you'd think that stronger bonds are more stable, correct? But in this case, the stronger bonds in alkenes/alkynes have higher bond energy and thus more unstable than alkanes.

Why alkanes are most stable?

Alkanes are not very reactive when compared with other chemical species. This is because the backbone carbon atoms in alkanes have attained their octet of electrons through forming four covalent bonds (the maximum allowed number of bonds under the octet rule; which is why carbon's valence number is 4).

Is E or Z alkene more stable?

Therefore, generally speaking, the trans (E) isomers are more stable and lower in energy than the cis (Z) isomers.

Which is more stable ethene or propene?

Statement-II : Propene is more stable than ethene.

Which one is correct for stability order?

I > III > II.

Which element is the most stable?

There are some 90+ elements of the periodic table that occur naturally in the Universe, but of them all, iron is the most stable. If you fuse lighter elements together to get closer to iron, you gain energy; the same is true if you split heavier elements apart.
