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

$\therefore \text{Total} \, \text{moles} \, \text{2} \, \text{+} \, \text{2} \, \text{+} \, \text{4} \, \text{=} \, \text{8}$
