    Bond angles in Chemistry?

    one more thing guys.. why is C-Cl bond the weakest when compared to C-H and C-F ...for C-F what i thnk is bcz F is more electronegative, it attracts the bonded pair towards itself n so more strength of the bond, is it right?...but why C-Cl is bein chosen over C-H?? ! :S
