Vedclass · Answer

(C) The reaction of an alcohol $(ROH)$ with methyl magnesium iodide $(CH_3MgI)$ produces methane gas $(CH_4)$:$ROH + CH_3MgI 	o CH_4 \uparrow + Mg(OR)I$According to the stoichiometry,$1 \, mol$ of alcohol produces $1 \, mol$ of $CH_4$ gas.At $STP$,$1 \, mol$ of any gas occupies $22400 \, mL$.Given that $1.12 \, mL$ of $CH_4$ is produced from $4.12 \, mg$ of alcohol.Therefore,$22400 \, mL$ of $CH_4$ would be produced by:$	ext{Molecular mass} = \frac{4.12 \, mg}{1.12 \, mL} 	imes 22400 \, mL/mol$$= 4.12 	imes 20000 \, mg/mol = 82400 \, mg/mol = 82.4 \, g/mol$.Thus,the molecular mass of the alcohol is $82.4 \, g/mol$.

$1.12 \, mL$ of a gas is produced at $STP$ by the action of $4.12 \, mg$ of alcohol with methyl magnesium iodide. The molecular mass of the alcohol is:
