Isopentane can form four structurally isomeric mono bromo derivatives.

1.	Isopentane can form four structurally isomeric mono bromo derivatives. How many of them are cally active?
Answer» 1<BR>2 3 4 Solution :Mono bromo derivatives of ISO pentane are 1) `CH_(3)-overset(CH_(3))overset(\|)CH-CH_(2)-CH_(2)-Br` `CH_(3)-underset(Br)underset(\|)overset(CH_(3))overset(\|)C-CH_(2)-CH_(3)` Among (4) isomers TWO are optically active due to the PRESENCE of chiral CENTRE
