HCl is a polar compound, Why HCl shows polar nature?

Consider the case hydrogen Chloride molecule [HCl] The chlorine atom with a higher electronegativity attract the shared pair of electrons towards its nucleus. As a result the chlorine atom in hydrogen chloride develops a partial negative charge delta^- (delta negative) and hydrogen atom develops a partial positive charge delta^+ (delta positive) it can be represented below.

Electronegativity values of elements help in predicting :- strength of the element, polarity of the molecules, śize of the molecules, valency of the elements

Assertion : Statement -1 : The direction of dipolemoment in CO molecule is from oxygen to carbon Reason : Statement - 2 : The contribution of co-ordinate pi bond is more compared to electronegativity factor in the overall polarity of the molecule. (1) Statement-1 is true , statement -2 is true and statement-2 is the correct explanation for statement - 1. (2) Statement-1 is true, statement -2 is not the correct explanation for statement -1 . (3) Statement -1 is true, statement 2- is false (4) Statement -1 is false , statement-2 is true
