Which alkane is Monochlorination?
Which alkane is Monochlorination?
Complete answer: Monochlorination of an alkane involves substituting one of the hydrogen in the alkane with a chlorine atom. This is achieved by treating the alkane with chlorine in the presence of UV light. These conditions cause the chlorine molecule to split into chlorine free radicals.
What is meant by Monochlorination?
noun. Chemistry. The action or process of introducing a single chlorine atom into a molecule.
How many Monochlorination products are possible?
Total fourteen monochlorinated products can be obtained from all the isomeric alkanes having the formula C5H10 (excluding stereoisomers).
What is necessary for chlorination of an alkane?
Energy input in the form of heat or light is necessary to initiate these halogenations. If light is used to initiate halogenation, thousands of molecules react for each photon of light absorbed.
What are the 3 isomers of C5H12?
Pentane (C5H12) is an organic compound with five carbon atoms. Pentane has three structural isomers that are n-pentane, Iso-pentane (methyl butane) and neopentane (dimethylpropane).
What is the mechanism of halogenation of alkanes?
What is the nature of the mechanism of halogenation of alkanes? In the presence of ultraviolet (UV) light or heat, the reaction of a halogen with an alkane results in the formation of a haloalkane (alkyl halide).
Are constitutional isomers?
Constitutional isomers are molecules of different connectivity—analogous to simple bracelets in which the order of red and green beads is different. The second type is stereoisomers. In stereoisomers the connectivity is the same, but the parts are oriented differently in space.
How many Monochlorination products are possible for Neopentane?
Therefore, the compound which gives only one monochlorination product on its chlorination in the presence of sunlight is neopentane. So, option (C) is the correct answer. Note: It is important to note that stereoisomers of the products are not included here.
How many Monochlorination products are possible for butane?
It depends on the substitution of hydrogen atom. So, there can be 4 monochlorinated products of 2 methylbutane.
How many Monochlorination products are possible for n butane?
A chiral centre is a carbon that has different groups attached in different sides. The compound is optically active and has 2 stereoisomers. So, if the question had asked for monochlorination products including stereoisomers, there would have been 3 products of n-butane.
What are the 3 types of alkane reactions?
However, there are a few classes of reactions that are commonly performed with alkanes.
- Oxidation Reactions. The most important reaction that alkanes undergo is combustion.
- Halogenation.
- Thermal Cracking.
Why are alkanes unreactive?
Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from their reaction with oxygen in the air – which we call burning or combustion.
How is the Monochlorination of an alkane achieved?
Monochlorination of an alkane involves substituting one of the hydrogens in the alkane with a chlorine atom. This is achieved by treating the alkane with chlorine in the presence of UV light. Theses conditions cause the chlorine molecule to split into chlorine free radicals.
What makes an alkane different from other compounds?
The distinguishing feature of an alkane, making it distinct from other compounds that also exclusively contain carbon and hydrogen, is its lack of unsaturation. That is to say, it contains no double or triple bonds, which are highly reactive in organic chemistry.
Why is the valence number of alkanes 4?
This is because the backbone carbon atoms in alkanes have attained their octet of electrons through forming four covalent bonds (the maximum allowed number of bonds under the octet rule; which is why carbon’s valence number is 4). These four bonds formed by carbon in alkanes are sigma bonds.
How many hydrogen atoms are in propane Monochlorination?
Propane, for example, contains six primary and two secondary hydrogen atoms. The hydrogen type most likely to be substituted in a radical monochlorination is the one that has three times more 1-chloropropane molecules formed than 2-chloropropane molecules.
