One litre N2,78litre  O2{\mathrm{N}_2},\frac{7}{8}\mathrm{litre}\;{\mathrm{O}_2} and 1 litre COCO are taken in a mixture under indentical conditions of P and T. The amount of gases present in mixture is given by:
View answer and explanation
Correct option: C
wN2=wO2=wCO{w_{{\mathrm{N}_2}}} = {w_{{\mathrm{O}_2}}} = {w_{\mathrm{CO}}}
Option D is correct because boron in H2C=CH−B⊕H3{H_2}C = CH - \mathop B\limits^ \oplus {H_3} has a positive charge and lacks a vacant orbital, preventing resonance.
