Any atom, group, or radical substituted for another, or entering a molecule in place of some other part which is removed.
What else can I help you with?
Is the substituent SO3H ortho para directing?
Yes, the substituent SO3H is ortho para directing.
What substituents have a positive Hammet substituent constant?
Substituents with a positive Hammet substituent constant are electron withdrawing. Examples include CF3.
What substituents have a negative Hammet substituent constant?
Substituents with a negative Hammet substituent constant are electron donating. Examples include R groups and OH groups.
What is iodine called when it's a substituent on a carbon skeleton?
Iodine is called an iodo substituent when it is attached to a carbon skeleton in organic chemistry. It is commonly represented by the symbol I.
How many substituent groups can obtained by removing a hydrogen atom from propane?
Two substituent groups can be obtained by removing a hydrogen atom from propane, resulting in propyl groups.
What is the Hammet substituent constant?
The Hammet substituent constant shows the electron donating or accepting nature of the molecule as well as its chemical reactivity. It is often used in the QSAR study of drugs.
Which orientation, equatorial or axial, is more stable in terms of energy for a substituent in a cyclohexane chair conformation?
The equatorial orientation is more stable in terms of energy for a substituent in a cyclohexane chair conformation.
Is it possible to draw cis- and trans- stereoisomers for some aliphatic alkanes?
Yes. When the aliphatic alkanes have a ring structure containing 2 substituent groups, the cis-isomer occurs when both substituent groups are on the same side of the plane while the trans-isomers occurs when the substituent groups are on different side of the plane.
What are the key differences between molecules in the R configuration versus S configuration?
The key difference between molecules in the R configuration and S configuration is the way their substituent groups are arranged around a chiral center. In the R configuration, the highest priority substituent is on the right side, while in the S configuration, the highest priority substituent is on the left side. This arrangement is determined by the Cahn-Ingold-Prelog priority rules based on the atomic number of the substituent atoms.
Is oxalic acid and lithium oxalate a proper buffer substituent pair?
Yes
What is an amphopropionate?
An amphopropionate is an amphoteric propionate, especially a salt of a propionic acid which has a basic substituent.
What is an amphoacetate?
An amphoacetate is an amphoteric acetate, especially a salt of an acetic acid which has a basic substituent.
