(a) nitroethane
(b) 2-methyl-1-nitropropane

Explanation

(a) `underset("Nitroethane")(CH_(3)-CH_(2)-NO_(2))overset(LiAIH_(4)//"ether")rarr underset("Ethanamine")(CH_(3)-CH_(2)-NH_(2))`
(b) `underset("2-Methyl-1-nitropropane")(CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)-NO_(2)) overset(LiAIH_(4)//"ether")rarr underset("2-Methylpropanamine")(CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)-NH_(2))`
