JEE Main 2024 — 4 April, Shift 2 — Question 77

Number of compounds/species from the following with non-zero dipole moment is $\qquad$

$\mathrm{BeCl}_{2}, \mathrm{BCl}_{3}, \mathrm{NF}_{3}, \mathrm{XeF}_{4}, \mathrm{CCl}_{4}, \mathrm{H}_{2} \mathrm{O} \mathrm{H}_{2} \mathrm{~S}, \mathrm{HBr}$ , $\mathrm{CO}_{2}, \mathrm{H}_{2}, \mathrm{HCl}$

Answer: 5

Numerical answer — enter this value.

Step-by-step solution

Polar molecule: $\mathrm{NF}_{3}, \mathrm{H}_{2} \mathrm{O}, \mathrm{H}_{2} \mathrm{~S}, \mathrm{HBr}, \mathrm{HCl}$ $(\mu \neq 0)$

Non Polar molecule: $\mathrm{BeCl}_{2}, \mathrm{BCl}_{3}, \mathrm{XeF}_{4}, \mathrm{CCl}_{4}, \mathrm{CO}_{2}, \mathrm{H}_{2}$ $(\mu=0)$
