Alkanes Alkenes Alkynes General formula CH n H 2n+2 CH n H 2n CH n H 2n-2 Naming All the members end with 'ane' All the members end with 'ene’ All the members end with 'yne’ Physical state Members having 1-4 carbon atoms ..
Unsaturated Hydrocarbons Alkenes and Alkynes
When the hydrogen to carbon ratio is less than that required for alkanes in hydrocarbons, they are called as unsaturated hydrocarbons. The valencies of carbon atoms in these compounds are satisfied by the formation of a double (=) triple ( ) bonds. Compounds containing a double bond are called ..
From alkynes
Alkenes can be easily obtained by hydrogenation of alkynes. An alkyne on controlled hydrogenation with hydrogen in the presence of Ni or Pd at 200C give corresponding alkene. C n H 2 n - 2 + H 2 ..

Alkynes (earlier called acetylenes), are those unsaturated hydrocarbons containing a carbon-carbon triple bond (-C C-). A general formula C n H 2 n - 2 , can represent alkynes. Alkynes posses four hydrogen atoms less than the alkane and two hydrogen atoms less..

General Chemical Properties of Alkynes
Carbon-carbon triple bond, C=C, is a combination of one and two bonds. Alkynes give electrophilic addition reactions as they show reactivity due to the presence of bonds. This property is similar to alkenes but alkynes are less reactive than alkenes tow..
Acidic hydrogen in 1-alkynes
Hydrogen atoms in ethyne and 1-alkynes, linked to the carbon atom having a triple bond on it, are acidic in nature. For example, ethyne (acetylene) is a weak acid: weaker than water but stronger than ammonia. This may be explained as follows: The -electrons are more weakly bound than ele..

I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Even though I don't feel good, the tutor helped me by totally helping me understand!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Looking for More Help!
