What are the intermolecular forces in it?
what is the molar mass?

2 propanol: the "prop" tells you there are 3 carbon atoms (that makes it an organic compound). The "-ol" ending tells you it is an alcohol (confirms this is organic). The "2" tells you the -OH group (which is common to the alcohols) is on the 2nd carbon.
The molecule looks like this: (ignore the dots; I needed them to hold the spaces between the H's).
.. H...OH..H
H-C---C---C-H
.. H... H... H
All of the bonds (12) are sigma bonds (don't forget there is a bond between the O and the H) and they are polar covalent bonds.
Its molecular mass is the individual atomic masses (you find them on the periodic chart) added up. Since there are 3 carbons, one oxygen and eight hydrogens the mass would be:
3 x C plus 1 x O plus 8 x H
(3 x 12) + 16 + (8x1) = 60 g/mol

The intermolecular forces between propan-2-ol molecules are called hydrogen bonds, and account for the relatively high boiling point of this compound.

Propanol, C3H7OH, is organic because it has carbon in it. it has one sigma bond, and the intramolecular forces include covalent bonds, and the molar mass is 60
