Leah4sci.com Ester Functional Group -COOR. The ester functional group has an oxygen double-bound to carbon (carbonyl) along with an OR group attached to the same carbon. The ester is a carboxylic acid derivative in which the OH is replaced by an OR. Do not confuse esters with ethers despite the names AND groups being so similar. end group: functional group at the end of a chain in polymers, e.g. carboxylic group. extrusion: a fabrication process in which a heat-softened polymer is forced continually by a screw through a die. filler: a relatively inert material used as the discontinuous phase of a polymer composite.
Jan 17, 2015 · Here “OH” is a functional group . so in parent chain it must be included. The numbering of carbon atoms in parent chain is done in such a way that the carbon atom bearing the functional group gets the lowest number. All the other rule for naming the substituent ( or side chain) are followed . These are the same as describe earlier .

However, the name 2-hydroxyethanamine unambiguously refers to the same compound. How the name was constructed: There are two carbons in the main chain; this gives the root name "eth". Since the carbons are singly-bonded, the suffix begins with "an". The two functional groups are an alcohol (OH) and an amine (NH 2). -

Imagine that you’ve got an ester. Remember that the general structure is COOR. What they consider is that everything on this side is an alkyl group. You name this as an alkyl group. Then the way that they name the other side is they think this looks a lot like, this side here, looks a lot like a carboxylic acid but without the H.
When compounds contain more than one functional group, the order of precedence determines which groups are named with prefix or suffix forms. The highest precedence group takes the suffix, with all others taking the prefix form. However, double and triple bonds only take suffix form (-en and -yn) and are used with other suffixes.
