How many R-groups are directly attached to the nitrogen atom of a tertiary amine?
A tertiary amine has three R-groups directly attached to the nitrogen atom.
What is R-O-R in chemistry?
R-O-R in chemistry represents an ether functional group, where R can be any organic substituent. Ethers are characterized by an oxygen atom connected to two alkyl or aryl groups. They are commonly used as solvents and have low reactivity compared to other functional groups.
Do all amino acids have R groups that are polar?
Yes, all amino acids have the same basic composition, though the r-groups causes the variation. There are 20 different amino acids.
How many different groups of 3 people can be formed from a group of 5 people?
There are 10 different groups of 3 people that can be formed from a group of 5 people. This can be calculated using the combination formula, which is nCr = n! / r!(n-r)!, where n is the total number of people and r is the number of people in each group.
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.
How many groups of 19 go into 127?
R
How many R-groups are directly attached to the nitrogen atom of a tertiary amine?
A tertiary amine has three R-groups directly attached to the nitrogen atom.
How many groups of 20 can you choose out of 23?
Combinations of r from n without replacement is c(n,r) = n!/(n-r)!r! c(n,r) = 23!/20!3! c(n,r) = 1771.
How many 'R' groups are bonded to the carbinol carbon of a secondary alcohol?
Two "R" alkyl groups are attached to carbinol carbon in secondary alcohlos

What do r-groups give proteins?
They give them their shape.
What is the general formula of ester?
The general formula of an ester is RCOOR', where R and R' represent alkyl or aryl groups. It consists of a carbonyl group (C=O) bonded to an oxygen atom, which is in turn bonded to another carbon atom. Ester groups are commonly found in fats, oils, and many fragrant compounds.
What type of molecule has a very long helical molecule made of units with distinctive r-groups?
A protein molecule has a long helical structure made of amino acid units with distinctive R-groups. The R-groups contribute to the unique 3D structure and function of the protein.
