Two ethyl groups, one over here and one right over here.

So we know that this right here, this is an ethyl group.

Let me add another ethyl group to it.

It's on the five carbon, so that is a 5 ethyl.

So let's say we have another ethyl group over there.

Or two ethyl groups, I should say, not ethane groups.

1 Bromobutane (CH3(CH2)3Br) is a colorless liquid that is insoluble in water, but soluble in ethanol and diethyl ether.

If methyl is one, ethyl is two, propyl is three, butyl is four, so this is a three carbon group, and it's going to be attached to the second carbon on the heptanes.

Use of oil with tetra ethyl lead causes much pollution, with lead containing carbon monoxide, nitrogen oxide and policyclic nitro hydride.

And this is not just philosophical, it's already known, that chemicals like diethylstilbestrol and estrogen, cross the placenta and effectively determine the likelihood of developing breast cancer and obesity and diabetes already when the baby's in the womb.
