The oxygen draws electron density away from the carbon chain, making the molecule more polar. However in larger chains the effect is less. Soluble due to Hbonding. bp is higher than the alkane due to interactions.

Physical properties of thiols.
Compound with -SH group. the sulfur can form disulfide bridges, but less polar. Thiols have a strong repulsive odour.
2 of 8
Physical properties of ethers.
R-O-R. can form h-bonds with water. Weaker forces than alcohols.
3 of 8
Physical properties of aldehydes and ketones.
Can't form h-bonds with self, only water. polar molecules.
4 of 8
Physical properties of carboxylic acids
very polar molecule, strong interaction between molecules very high bp.
5 of 8
Physical properties of esters.
No h-bonding between but water soluble
6 of 8
Physical properties of amines and amides.
N-H group can form two h-bonds as oppose to 1. so more polarity than carboxylic acids. c=o-NH2 - amide has c=o group. amines can form opitcal isomerism. primary amine most soluble as more h-bonds to water.

Physical properties of guanidinum group.
NH2-c(=NH2)-NH2 strong base, commonly used to denature proteins.
