Question * bonus. (to reveal the answer click on the question)

All of the following questions refer to the picture of the molecular model on the right hand side:

(i) Draw the full structural formula

(ii) Write out the molecular formula.

C4H8O2

(iii) Write out the condensed structural formula representation.

C4H6(OH)2 - (rings are kept intact in the representation. In this case the C4H6 represents the hydrocarbon ring)

(iv) What is the full systematic name of the molecule?

trans-cyclobutan-1,3-diol

(v) What kind(s) of intermolecular forces does this molecule experience?

Dispersion forces (induced dipole-dipole), Hydrogen bonding. Can you see why there is no permanent dipole?
