Hello,

You are talking about homologous series. Is it correct to say that organic compounds with the same molecular formula does not necessarily belong to the same homologous series?

Hi chaocheng,


Yes, you are precisely right. This is a good point to remember since many commits error because of this.

An example is the molecular formula C2H4O2. This can be ethanoic acid or methyl methanoate. These two compounds belong to different homologous series carboxylic acid and ester.

What do you think are the pros and cons in getting help from a chemistry tuition? Need to collect this to decide whether to get one or not.
