发帖数: 8 | 1 pls don't laugh at me. My chemistry is total rubbish.
Anyone can tell me what's the meaning of *C (star on left top of Carbon atom)
in a carbon chain, and what's then meaning of a black point above on the
Carbon atom.
Also how to say in Chinese that 'steric effect', and the meaning.
Sorry I can't input Chinese. Anyone could tell me the answer in Chinese will
be most help!
Thx a lot! | b***e

发帖数: 238 | 4 If I remember correctly, the radical is usually represented by a dot,
I hardly remember anything related with an asterisk, maybe an asymmetric
carbon atom, or an isotopic carbon.
steric effect译为位阻效应吧.
It is generally caused by the hindrance of large groups.
