What is the major product of the following reaction? NaOH Calitinns Am

Answer 1

1)

The major product of the reaction is shown below.

$1596211889588_image.png$

The mechanism is shown below.

O O NaOH oooolto

2)

The eletron donating group on diene increases the reactivity.

Cyclic dienes, on the other hand, are ‘locked’ in the s-cis conformation, and are especially reactive than acyclic dienes.

Hence the reactivity of the dienes starting with fastest is shown below

.

> > > IV III I II not reactive it is non conjugated diene as

3)

Nao + NaNH2 "NH2

The above reaction does not occur because

acetate ion is more stable than ^-NH₂ ion due to atom trend.

4)

The major product of the reaction is shown below.

CH3 HO.

The mechanism of the reaction is shown below.
