All alkenes have a general formula of CnH2n (where n is the number of carbon atom, n=1 n=2 n=3). This general formula is different from alkane in terms of the number of hydrogen. Alkene molecules have two fewer hydrogen atoms than an alkane molecule with the same number of carbon atoms. The functional group of … Read moreAlkenes


Alkanes Alkanes are one of the four homologous series of organic chemistry. Homologous series are like families of organic compounds that have the same characteristics. A functional group is a group of atoms that gives characteristic properties of an organic compound. This is because the function group are the one that is involved in chemical … Read moreAlkanes
