What is vapour pressure of solution containing $$1.8 \mathrm{~g}$$ glucose in $$16.2 \mathrm{~g}$$ water?

($$\mathrm{P}_1^0=24 \mathrm{~mm} \mathrm{Hg}$$ and Molar mass of glucose $$=180 \mathrm{~g} \mathrm{~mol}^{-1}$$)

The rate law equation for a reaction between $$\mathrm{A}, \mathrm{B}$$ and $$\mathrm{C}$$ is $$\mathrm{r}=\mathrm{k}[\mathrm{A}][\mathrm{B}][\mathrm{C}]^2$$, what will be ne rate of reaction if concentration of both $$\mathrm{A}$$ and $$\mathrm{B}$$ are doubled.

Identify product $$\mathrm{C}$$ in following conversion.

m - Hydroxy Benzaldehyde $$ \xrightarrow[\text { [Protection of }-\mathrm{OH} \text { group] }]{\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{Cl}} $$ $$ \mathrm{A} \xrightarrow{[\mathrm{O}]} \mathrm{B} $$ $$ \xrightarrow[\text { [deprotection of }-\mathrm{OH} \text { group] }]{} $$ C

Which of the following is NOT dihydric alcohol?
