Re: The meaning of "dihedral"

the dihedral angle is the angle made by 4 consecutively covalently connected atoms. as for newman, these angles are commonly 0, 60, 120, and 180 and help to determine the positions of the the C, H, and other substituents.

Re: Nucleophiles

yes bc anions have negative charges due to them gaining electrons; therefore they would be electron rich. however, nucleophiles don't always have to have a negative charge.

Re: Post All Chemistry Jokes Here

In a sports relay race, a chemical kinetics specialist runs slowly, and his group loses the race.

When the chemical kinetics specialist is asked why he ran slowly, his reply was “I always wanted to be the significant rate determining step”.

balancing redox reactions

by just looking at the equations, how do you know when you need to add H+ and H20 instead of just adding electrons?

Re: units for pressure [ENDORSED]

from my experience, we typically use atmospheres for our calculations. if it is not given, then it is best to convert it to atmospheres.
