The acid formed when propyl magnesium bromide is treated with CO_2 followed by acid hydrolysis is:
The best reagent for converting propanamide into propanamine is:
Let $ P_n = \alpha^n + \beta^n $, $ n \in \mathbb{N} $. If $ P_{10} = 123,\ P_9 = 76,\ P_8 = 47 $ and $ P_1 = 1 $, then the quadratic equation having roots $ \alpha $ and $ \frac{1}{\beta} $ is:
