    Yea thats what thought..

    Your J is wrong. There are 3 carbon atoms so hence there should 3 oxygen atoms. The structural formula wud be CH3CH(OH)COOH.

    ^thats right. To find the oxidation state always make an equation. For example NH3. The overall charge is 0 and you have to find the oxidation number of nitrogen. hence let the oxidation number of nitrogen be x. Oxidation number of hydrogen is +1 and there are 3 atoms in total. so X+ ( 1 x...

    Yup they are Van der Waals! Hahaha well ure not the only one who's been there!

    Hahaha yea sorry. Apart from Hydrogen Bonds, the rest are known collectively as Van der Waals forcces;)

    Sorry not ALL intermolecular forces are Van der Waals. Hydrogen Bond is not included in Van der Waals forces.

    no no ure getting confused. All intermolecular forces are collectively known as Van der Waal's forces. The various different types were first explained by different people at different times. Dispersion forces that are temporary and induced dipoles were first introduced by London in i think 1930...

    No hydrogen bond is formed only when hydrogen is directly bonded to fluorine, nitrogen or oxygen.

    Yea thats permanent dipole dipole interaction but what i meant was that Van der Waal's forces comprise of 2 types of forces. One is dipole dipole interactions and the other is dispersion forces(aka temporary induced dipoles or London forces);)

    2 and 3 both are Van der Waals forces.;)

    Ure Welcome.:)

    Ionic bonding is not included in intermolecular forces. Thats intra-molecular forces.
