Esters

The longest continuous carbon chain

The one that bonds to both the -O and the =O

The one that bonds to only the -O

The one that bonds to only the =O

Whichever one I feel like!

Hydrogen bonds and LDFs to anything

Dipole-dipole forces and LDFs to anything

Hydrogen bonds to solvents that can make hydrogen bonds (like water), dipole-diple and LDFs to themselves

LDFs only
