    From my understanding you can have a polar bond but a non-polar molecule if it is symmetrical and has no lone pairs.As the dipoles would cancel out.However HCl is which I don't understand why as it is symmetrical and has no lone pairs so shouldn't the dipoles cancel out?

    Nonpolar molecules occur if it is symmetrical and has no lone pairs or the outer atoms are the same as the central atom so there is no overall charge as the charges are exactly the same

    HCl isn't symmetrical. Have another look at it.
