(a)
Interpretation:
The constitutional isomer, which is formed greatest yield in the given reaction should be given.
Concept introduction:
Dehydration reaction:
Removal of water molecule from the reaction when the alcohol is treated with strong acid like sulfuric acid is known as dehydration reaction, for example
Alcohols are react with acids like hydrochloric acid or hydrobromic to yields the corresponding carbocation intermediates, this carbocation intermediate undergoes elimination reaction to give a corresponding
The stability of carbocation is given below,
Tertiary carbocation is more stable than the secondary and primary.
Cis–trans isomerism (or) geometric isomerism or configurational isomerism:
The
The functional groups are in opposite to each other in the carbon chain is called trans isomer.
Two similar functional groups are in same side which is called as Z-isomer.
Two similar functional groups are opposite side which is called as E-isomer.
Stereoisomers: same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
(b)
Interpretation:
The stereoisomer, which is formed greatest yield in the given reaction should be given.

Dehydration reaction:
Dehydration reaction:
Removal of water molecule from the reaction when the alcohol is treated with strong acid like sulfuric acid is known as dehydration reaction, for example
Alcohols are react with acids like hydrochloric acid or hydrobromic to yields the corresponding carbocation intermediates, this carbocation intermediate undergoes elimination reaction to give a corresponding alkene as a product.
The stability of carbocation is given below,
Tertiary carbocation is more stable than the secondary and primary.
Cis–trans isomerism (or) geometric isomerism or configurational isomerism:
The functional groups are in the same side of the carbon chain is called cis isomer.
The functional groups are in opposite to each other in the carbon chain is called trans- isomer.
Two similar functional groups are in same side which is called as Z-isomer.
Two similar functional groups are opposite side which is called as E-isomer.
Stereoisomers: same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
