1H-H is having more enthalpy than D-D.Because the mass of hydrogen atom is lesser than deuterium.
1So if you hold a box in your hand it will not fall.And if you hold a car in your hand it will fall and the bond between you and the car wil break.So here it happens the same.
39If you go by that logic Vinay, your hand and the box/car do not consist of the same kind of molecules, and hence do not have that kind of bond.
