Draw the structures of the following :
(I ) 3-Bromo -4- phenylpentanoic acid (ii ) Hex -2- en 4- ynoic acid

Explanation

(i) `overset(5)(C)H_(3)-underset(C_(6)H_(5))underset(|)overset(4)(C)=underset(Br)underset(|)overset(3)(C)-CH_(2)-COOH`
(ii) `overset(6)(C)H_(3)-overset(5)(C)-=overset(4)(C)-overset(3)(C)H=overset(2)(C)H-overset(1)(C)OOH`
