(a)
Interpretation:
The carbocation intermediate formed during E1 reaction for each of the given substrates is needed to be drawn and in that the primary, secondary and tertiary carbocation should be identified with explaining the reason for one of the substrate’s inactivity in E1 reaction.
Concept introduction:
E1 reaction is a unimolecular elimination reaction in which carbocation is formed as an intermediate from substrate by the removal of leaving group and it has stepwise mechanism.
The first step of E1 reaction involves the removal of leaving group (halo-group) and the formation of carbocation. The
The stability of carbocation is in the increasing order of

The first step of E1 reaction involves the removal of leaving group (halo-group) and the formation of carbocation. The rate of E1 reaction is totally depends upon the nature of the substrate on the basis of stability of the carbocation formed from the alkyl halide.

Primary alkyl halides are generally does not undergo E1 reaction because of the very less stabled primary carbocation with high activation energy.
