Unit Alcohols and Ethers Key answer . R - OH + 2Na RONa + H ↑ moles of alcohol gives mole of H which occupies .4L at 273K and atm ∴ number of moles of alcohol = moles of R - OH . L of H × mL = . moles ∴ ⇒ no.
of moles = mass molar mass molar mass = g mol − General formula for R - OH C H - OH n 2n+ ∴ n( ) + (2n+ ) ( ) + + = 14n = - 14n = n = ∴ The alcohol which contains carbon is CH CH(OH)CH CH Option (a) .
