What is the general structure of alkanes?
Structure of Alkanes Alkanes have the general formula CnH2n+2. For example, an alkane with 2 (n) carbon atoms, will have 6 (2n + 2) hydrogen atoms. Their adjacent atoms are connected with sigma bonds and form tetrahedral centers around the carbon atoms.
What is general molecular formula?
A general formula is a type of empirical formula that represents the composition of any member of an entire class of compounds. Every member of the class of paraffin hydrocarbons is, for example, composed of hydrogen and carbon, the number of hydrogen atoms always being two…
What is the general formula of alkynes?
Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings).
What is general formula of alkenes?
Alkenes are defined as either branched or unbranched hydrocarbons that possess at least one carbon–carbon double bond (CC) and have a general formula of CnH2n [1].
Is general formula the same as molecular formula?
The molecular formula expresses information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers. Although a molecular formula may imply certain simple chemical structures, it is not the same as a full chemical structural formula.
What is the formula of Propyne?

Propyne/Formula
What is general formula of alcohol?
The general formula for the alcohols is C nH 2n+1OH (where n is the number of carbon atoms in the molecule).
What is the general formula of alkyl group?
An alkyl group is formed by removing one hydrogen from the alkane chain and is described by the formula CnH2n+1.
What is molecular formula and empirical formula?
An empirical formula represents the simplest whole-number ratio of various atoms present in a compound. The molecular formula shows the exact number of different types of atoms present in a molecule of a compound.
Which formula is the general formula for an alkane?
Alkanes have the general chemical formula C n H 2n+2 . The alkanes range in complexity from the simplest case of methane (CH 4 ), where n = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane (C 50 H 102 ) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (C 14 H 30 ).
Which is a molecular formula for an alkene?
Alkenes contain carbon-carbon double bonds and are unsaturated hydrocarbons with the molecular formula is C n H 2n; this is also the same molecular formula as cycloalkanes. Alkenes are named by dropping the -ane ending of the parent and adding -ene.
What is the formula for the alkanes?
The general formula for an alkane is C nH 2n+2 where n is the number of carbon atoms in the molecule. There are two ways of writing a condensed structural formula.
What is the molecular formula of alkene?
An alkene is a molecule made up entirely of carbon and hydrogen where one or more carbon atoms are connected by double bonds. The general formula for an alkene is C nH 2n where n is the number of carbon atoms in the molecule.
