In chemistry, an ethyl group is an alkyl substituent derived from ethane (C2H6). 1. 0 2. haight. Anonymous. This compound is highly volatile and flammable. In the case of ethyl ethanoate, for example, the ethyl group is listed before the name. Ethyl group — The portion of an organic molecule that is derived from ethane by removal of a hydrogen atom (– CH 2 CH 3). Such groups are often represented in chemical formulas by the letter R and have the generic name CnH2n+1. 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. The general molecular formula for simple alkyl groups is -C n H 2n+1 where n is the number of carbon atoms in the group. carbon chain which is to be considered has ethyl group as the substituent. The carbonyl group carbon has a sp 2 hybridization and the other part of the molecule has a tetrahedral geometry. methyl). ), and so on. The naming of esters can be confusing to students who are new to organic chemistry because the name is the opposite of the order in which the formula is written. Alkyl group definition, any of a series of univalent groups of the general formula CnH2n+1, derived from aliphatic hydrocarbons, as the methyl group, CH3−, or ethyl group, C2H5−. Ethyl group must be a substituent i.e. An alkyl group is a paraffinic hydrocarbon group that may be derived from an alkane by dropping one hydrogen from the structure. So an alcohol has an OH, an … C2H5 = Ethyl Group In chemistry, an ethyl group is an alkyl substituent derived from ethane (C2H6). The most commonly discussed ester is ethyl ethanoate. It has the formula –CH2CH3 and is very often abbreviated Et. Alkane is a functional group that has the general formula of CnH2n+2. Structure of Ethyl acetate – Structure Formula of Ethyl Acetate.
