Question

How many moles of Grignard reagent will consume when it reacts with following the compound?

Answer 1

Answer: 8

$(i)$ 2 acidic H-atom $(-OHand-SH)$ will consume 2 moles of $\text{RMgX}$ (acid base reaction)
$(ii)$ $\left(-CH=O\right),\left(-C\equiv N\right)$ group will consume 1 mole of $\text{RMgX}$ each = 2 moles
$(iii)$ and $\left(-\text{COOEt}\right)$ group will consume 2 moles of $\text{RMgX}$ each = 4 moles
$\therefore \text{Total}\text{moles}\text{2}\text{+}\text{2}\text{+}\text{4}\text{=}\text{8}$
