MCQ
A diatomic molecule has a dipole moment of $1.2 D$. If the bond distance is $1 \mathring A$, then fractional charge on each atom is.........$\times 10^{-1}$ esu.(Given $1 \mathrm{D}=10^{-18}$ esu $\mathrm{cm}$ )
- ✓$0$
- B$5$
- C$1$
- D$-1$
✓
Answer
Correct option: A.
$0$
a
$\mu=1.2 \mathrm{D}=\mathrm{q} \times \mathrm{d}$
$\mu=1.2 \mathrm{D}=\mathrm{q} \times \mathrm{d}$
$\Rightarrow 1.2 \times 10^{-10} \mathrm{esu} A=\mathrm{q} \times 1 A$
$\therefore \mathrm{q}=1.2 \times 10^{-10} \text { esu }$
