Question

An organic compound (A) contains only C , H and O atoms. On reaction with excess of CH 3 MgI, (A) gives a gas ( X ) whose volume under STP conditions was found to be 67.2 litre. The maximum number of hydroxyl groups in the compound (A) are (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

(67.2/22.4)= mole of gas (X) evolved =3 mole of gas (X) The number of active H- atom present in a molecule is equal to the number of moles of gas obtained i.e. no. of - OH groups in compound ( A )=3.

Q. An organic compound (A) contains only $C, H$ and $O$ atoms. On reaction with excess of $C H_{3} M g I$ , (A) gives a gas $(X)$ whose volume under $STP$ conditions was found to be $67.2$ litre. The maximum number of hydroxyl groups in the compound (A) are

$\frac{67.2}{22.4} =$ mole of gas $(X)$ evolved $= 3$ mole of gas $(X)$ The number of active H- atom present in a molecule is equal to the number of moles of gas obtained i.e. no. of $- O H$ groups in compound $(A) = 3$ .

Q. An organic compound (A) contains only C,H and O atoms. On reaction with excess of CH3​MgI, (A) gives a gas (X) whose volume under STP conditions was found to be 67.2 litre. The maximum number of hydroxyl groups in the compound (A) are

22.467.2​= mole of gas (X) evolved =3 mole of gas (X) The number of active H- atom present in a molecule is equal to the number of moles of gas obtained i.e. no. of −OH groups in compound (A)=3.
