Which of the following exhibits stereoisomerism? (i) 1,2-Dichloroethylene (ii) 2-Hydroxypropanoic acid (iii) 1, 1-Dichloroethylene (iv) 2-Methylpropane
1 (i) and (iv)
2 (ii) and (iv)
3 (i) and (ii)
4 (iii) and (iv)
Explanation:
1, 2-Dichloroethylene : It can show cis-and trans-forms. 2-Hydroxypropanoic acid : Due to presence of chiral carbon it can show optical isomerism. 1, 1-Dichloroethylene : It cannot show geometrical isomerism due to presence of similar groups on two double bonded carbon atoms. 2-Methylpropane : It cannot show optical isomerism due to achiral carbon. Hence, (1) and (2) will show stereoisomerism.
