Chemistry - Halogen Derivative Question with Solution | TestHub

• (P) is 2-bromo-2,3-dimethylbutane.
• (Q) is 2,3-dimethylbut-2-ene.
• (R) is 1-bromo-2,3-dimethylbutane.
• (S) is 1-iodo-2,3-dimethylbutane.

Mole of $\mathrm{P}=\frac{1}{10}\times \frac{50}{100}$

Mole of $\mathrm{Q}=\frac{1}{10}\times \frac{50}{100}\times \frac{80}{100}$

Mole of $\mathrm{R}=\frac{1}{10}\times \frac{50}{100}\times \frac{80}{100}\times \frac{50}{100}$

Mole of $\mathrm{S}=\frac{1}{10}\times \frac{50}{100}\times \frac{80}{100}\times \frac{50}{100}\times 1=0.02$ mole

1 mole of S has 127 gm of Iodine So 0.02 mole of S has 2.54 gm of Iodine.
