The
functional group found in an ester is a carbonyl group with an attached second oxygen
atom that is bonded to a carbonyl carbon substituent by a single bond, usually
a pair of alkyl or aromatic groups. In addition, it can be shown in
text as RCOOR or occasionally as ROCOR, which made them responsible in the <span>distinctive and attractive

An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one-OH (hydroxyl) group is replaced by an -O- akyl (alkoxy) group. Often esters are derived from a carboxylic acid and an alcohol. Therefore, -COO- is the ester functional group while that of carboxylic is -CO-OH, which makes carboxylic acids behave like carboxylic acids.
A meteor is an asteroid or other object that burns and vaporizes upon entry into the Earth's atmosphere; meteors are commonly known as "shooting stars." If a meteor survives the plunge through the atmosphere and lands on the surface, it's known as a meteorite.
