Question 13 NECO_MODEL_QUESTIONS_VOL1 • 2017 • CHEMISTRY • objective

The molecule \(\text{CH}_3\text{Cl}\) has a measured dipole moment of 1.87 D and a C-Cl bond length of 0.177 nm. (a) State the hybridisation of the carbon atom. (b) Assuming the dipole arises solely from the C-Cl bond, calculate the effective partial charge on chlorine in units of the elementary charge \(e\). (Use \(1\,\text{D}=3.33564\times10^{-30}\,\text{C·m}\) and \(e=1.602\times10^{-19}\,\text{C}\).)

Answer Options

Correct Answer A. sp³; effective charge on Cl ≈ 0.22 e
B. sp²; effective charge on Cl ≈ 0.15 e
C. sp; effective charge on Cl ≈ 0.22 e
D. sp³; effective charge on Cl ≈ 0.35 e
Correct Answer
A
Correct Option:
sp³; effective charge on Cl ≈ 0.22 e
