8.2 Organic chemistry isomerism — Chemistry STD 11 Science — Question

$A$. Compound ' $B$ ' is aromatic

$B$. The completion of above reaction is very slow

$C$. '$A$' shows tautomerism

$D$. The bond lengths $C - C$ in compound $B$ are found to be same

Choose the correct answer from the options given below :

$CH _{3} OH (1)+\frac{3}{2} O _{2}( g ) \rightarrow CO _{2}( g )+2 H _{2} O (1)$

the amount of heat produced as measured by bomb calorimeter is $726 \,kJ\, mol ^{-1}$ at $27^{\circ} C$. The enthalpy of combustion for the reaction is $- x \,kJ\,mol ^{-1}$, where $x$ is $.....$ (Nearest integer)

$\left(\right.$ Given $: R =8.3\, J\,K ^{-1} \,mol ^{-1}$ )

$(A)$ $\Delta S _{ x \rightarrow z}=\Delta S _{ x \rightarrow y}+\Delta S _{ y \rightarrow z}$

$(B)$ $w_{x \rightarrow z}=w_{x \rightarrow y}+w_{y \rightarrow z}$

$(C)$ $w_{x \rightarrow z \rightarrow z}=w_{x \rightarrow y}$

$(D)$ $\Delta S _{x \rightarrow y \rightarrow z}=\Delta S _{x \rightarrow y}$
