D. Viscosity of H₂O is greater than Δ₂O

(1) A, B and C only

(2) A and B only

(3) A and D only

(4) A and C only

Answer 1

(1) A, B and C only

Heavy water is used in exchange reactions for study of reaction mechanisms

Heavy water is prepared by exhaustive electrolysis of water.

B.P. of Δ₂O = 374.4 K

B.P. of H₂O = 373 K

Viscosity of H₂O = 0.89 centipoise

Viscosity of Δ₂O = 1.107 centipoise
