What is suffix of carboxylic acid?
In general, carboxylic acids are named based on the number of carbons in the longest continuous chain, including the carboxyl group (-COOH). The suffix of this carbon chain is then replaced, as carboxylic acids always end in "-oic acid." An example is CH2O2, in which the longest continuous carbon chain is a methane.
What is the suffix of ketone?
They are named by finding the carbonyl group and identifying it with a location number, if necessary, then adding the suffix "-one." The common name for ketones is determined by naming the alkyl groups attached to the carbonyl (in alphabetical order), then adding 'ketone'.
What does the suffix one mean in chemistry?
ketoneThe suffix -one is used in organic chemistry to form names of organic compounds containing the -C(=O)- group: see ketone. Sometimes a number between hyphens is inserted before it to state which atom the =O. atom is attached to. This suffix was extracted from the word acetone.

Halogen substituents are also indicated using prefixes, such as fluoro (F-), chloro (Cl-), bromo (Br-), and iodo (I-). Numbers are used to identify the position of the substituent. For example, (CH 3) 2 CHCH 2 CH 2 Br is named 1-bromo-3-methylbutane.
What is the root name of a hydrocarbon?
