alkane alkene or alkyne

Alkanes, alkenes, alkynes, alcohols, aldehydes, carboxylic acids etc. form separate homologous serie..

-yne 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..

Question: Name two important uses of coal and petroleum. Answer: Coal is used as energy input in metallurgical operations like the making of iron and steel and for generating power plants. Petroleum is refined to make automobile and aviation fuels like petrol, diesel and kerosene. It is ..

Question: The open chain aliphatic hydrocarbon with molecular formula C 9 H 16 is _________. 1. an alkane 2. an alkene 3. an alkyne 4. acyclic Answer: ..

An alkyne reacts with hydrogen in the presence of catalyst (Pt or Ni) at 250°C, first forming alkenes and finally alkane. For example, ethyne gives ethane in two steps. ethyne etheneethane Ethane is obtained in good yields if hydroge..

These are hydrocarbons that contain at least one special type of hexagonal ring of carbon atoms with three double bonds in their alternate positions. The ring is called aromatic or benzene ring. For example, benzene, toluene, o-xylene. They also contain more than one benzene rings. For example, na..

Each member of this series differs from the previous one by an increment of -CH 2 - group. Thus, the methane family is a homologous series that can be characterised by the formula C n H 2n+2 . All members of this group can be prepared by the reduction of their appropriate alkyl halides (C n H 2n+1 ..

Question: Three hydrocarbons have molecular formula: a) 1) C 4 H 8 2) C 2 H 2 3) C 3 H 8 Identify them. b) Draw their structural formulae and give their IUPAC names. Answer: a) 1) In C 4 H 8 , n = 4 and it fits into the formula C n H 2n Therefore it is an alkene 2) In C 2..

Haloalkanes can be prepared from alkanes and alkenes when the halogen atom replaces the hydrogen ato..

Alkenes, like alkanes, are highly combustible. Alkenes burn with a luminous flame to give carbon dioxide and water. The flame becomes luminous because of the higher carbon content of alkenes than alkanes. Their combustion reactions are exothermic. ..
