Thanks so much, that is extremely helpful. I had looked up cinnamic acid, but I must have missed that entry. On the other one I looked up bromobenzoic...

Does anyone know the answer to this question: Both naphthalene and para-dichlorobenzene are effective moth repellents. What property of these chemicals allow...
Hi Obelisk! They are both solids that have high vapor pressures. This means that if you keep clothes in a plastic bag or in a closely- confined closet, and if...
Actually, all volatile hydrocarbons are toxic to insects, in sufficient quantity. For example, kerosine (along with mineral turpentine) is an old-fashioned...
Why, when this poor querent comes seeking information about naphthalene and p-dichlorobenzene, would some pedant hold forth about gasoline, kerosene, and...

I know this is pretty elementary, but I'm not quite getting this. We did a freezing point depression to determine formula mass using lauric acid as the...
Pardon: In my experience, mixing lauric acid (C12) with stearic acid (C18) would result in an unholy mess. The usual classic freezing point depression is with...
Long-chain carboxylic acids are much less ionized under ordinary conditions than, for example, acetic and formic acids, so much so that it is negligible. What...

Malononitrile is propanedinitrile or dicyanomethane. NC-CH2-CN Succinimide is pyrrolidine-2,5-dione. Dimethyl malonate (two words) is diethyl propanedioate. ...
Roger is correct that electrophilic is "electron-loving," where the electrons are in bonds, and positively charged reagents are attracted to them. An example...
An example of a nucleophilic addition reaction is the Michael reaction of carbanions with *alpha*,*beta*-unsaturated carbonyl compounds. For example, sodium...
