Solved: a. Draw the condensed structures and give the

Solution:

Here we have to draw the condensed structure of alkenes with molecular formula C6H12, then we have to write their systematic names and identify which has E or Z-isomer.

E and Z-isomer:- If two groups of higher priority are present on the opposite side of a double bond then it is said to be E-isomer whereas if the higher priority groups  are present on same side of a double bond then it is said to form Z-isomer.

Step 1

a. The molecular formula C6H12 can form the following isomers and the systematic names are written below the each isomers.

CH2=CH2CH2CH2CH2CH3     CH3CH=CHCH2CH2CH3        CH3CH2CH=CHCH2CH3

       (1-hexene)                        (2-hexene)                (3-hexene)
