Write the structural formulae for :
(i ) 4-Methylpent-2-ene
(ii) 2,2-Dimethylpropane
(iii) 2-Ethylpent-2-ene
(iv) Cyclohexene
(v) 1,3-Dimethylcyclohexane

Write the structural formulae for 4,6-dimethyl hept-2-ene

Write the structural formula of : (i) 2, 3-dimethylbutane (ii) 2-Methylpentane (iii) 2, 2,4-trimethylpentane.

The structural formula for 2-ethylprop-2-en-1-ol is :

Write the structural formula of 4-chloropent-2-ene.

Write the structure formulas for the following: (i) cis-Oct- 3 -ene (ii) 2,4 -Dimethylpent- 2 -ene (iii) 3,4 -Dimethylcyclopentene (iv) 1,3 -Dimethylcyclohexene (v) Vinylcyclopentane Strategy: first write down the parent C chain. Then introduce the double bond between the suitable C atoms. Finally attach the substituents and the suitable number of H atoms to satisfy the valency of C's . In cycloalkenes, one can write down the double bonds anywhere in the ring but the position of substituents is fixed by the position of double bonds.
