What is the general formula for an ester?
RCOOR′
Esters have the general formula RCOOR′, where R may be a hydrogen atom, an alkyl group, or an aryl group, and R′ may be an alkyl group or an aryl group but not a hydrogen atom. (If it were hydrogen atom, the compound would be a carboxylic acid.)
What is the general formula for alkane series?
C nH 2n+2
The general formula for the alkanes is C nH 2n+2 (where n is the number of carbon atoms in the molecule).
How do you name esters from a structural formula?
Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate. 1.
What is the formula for a fully saturated alkane?
A fully saturated hydrocarbon, an alkane, has general formula CnH 2n+2: n = 1, methane; n = 2, ethane; n = 3, propane. BY reason of their formula alkanes are said to HAVE NO DEGREES of UNSATURATION. Where the formula is CnH 2n or CnH 2nOm, each 2 hydrogens LESS than 2n+2 represents a degree of unsaturation.
What is the formula for the Alkane Cycloalkane?
Cycloalkane: CnH 2n A fully saturated hydrocarbon, an alkane, has general formula CnH 2n+2: n = 1, methane; n = 2, ethane; n = 3, propane. BY reason of their formula alkanes are said to HAVE NO DEGREES of UNSATURATION. Where the formula is CnH 2n or CnH 2nOm, each 2 hydrogens LESS than 2n +2 represents a degree of unsaturation.
How are alkanes named in the IUPAC nomenclature?
The IUPAC nomenclature (systematic way of naming compounds) for alkanes is based on identifying hydrocarbon chains. Unbranched, saturated hydrocarbon chains are named systematically with a Greek numerical prefix denoting the number of carbons and the suffix “-ane”.
Are there any other isomers of alkane Besides butane?
In addition to the alkane isomers, the chain of carbon atoms may form one or more rings. Such compounds are called cycloalkanes, and are also excluded from the above list because changing the number of rings changes the molecular formula. Cyclobutane and methylcyclopropane are isomers of each other, but are not isomers of butane.
