Geometry of `CHCl_(3)` is

Assertion: CHCl_(3) is more acidic than CHF_(3) . Reason: The conjugate base of CHCl_(3) is more stable than CHF_(3) .

The boiling point of CHCl_(3) was raised by 0.323^(@)C when 0.37 g of naphthalene was dissolved in 35 g CHCl_(3) . Calculate the molecular weight of naphthalene. (k'_(b) "for" CHCl_(3)= 3.9Kmol^(-1) kg) .

The oxidation of CHCl_(3) by air & light is prevented by adding -

The boiling point of C Cl_(4) higher than that of CHCl_(3) because :
