Question

R-C = C-R
LIAIH,
→ RCH
CHR'
In the above reaction, R and R' should be
O R = CHO and R = CH3
OR=CH, and R' = CH OH
O R=C2Hg and R = co
O R = CHg and R' = COOH​

Answer 1

Answer:

The order of stability of the alkenes is I>II>III>IV>V.

More substituted alkene is more stable than less substituted alkene.

Also, 1,1 - disubstituted alkene is more stable than 1,2-disubstituted alkene.
