1 Bromobutane 2 Bromobutane 2 Bromo 2 Methylpropane
Comparison of halogenated hydrocarbons
There are currently three halogenated hydrocarbons, namely 1-Bromobutane, 2-Bromobutane, and 2-Bromo-2-Methylpropane. These three have different structures and properties.
1 - Bromobutane, its carbon chain is straight chain, and the bromine atom is connected to the carbon atom at the end of the chain. Because of its relatively regular structure and small steric resistance, the halogen atom is easier to leave in the nucleophilic substitution reaction, and the reactivity is quite high. And because of its moderate molecular polarity and good solubility in certain solvents, it is often an important raw material in many organic synthesis reactions.
2 - Bromobutane, the carbon atom connected to the middle of the carbon chain. Compared with 1 - Bromobutane, its steric barrier is slightly larger. In the nucleophilic substitution reaction, the difficulty of the halogen atom leaving is between 1 - Bromobutane and 2 - Bromo - 2 - Methylpropane. Its chemical properties are both active and stable, and it is widely used in the field of organic synthesis. It can be converted into various organic compounds through various reaction pathways.
2 - Bromo - 2 - Methylpropane, the carbon atom connected to the bromine atom in the molecule is a tertiary carbon atom, with many surrounding methyl groups and great steric barrier. This structure makes it difficult for the halogen atoms to leave and the reactivity is relatively low in the nucleophilic substitution reaction. However, due to its special structure, under some specific reaction conditions, it can show unique reaction properties, providing a different path for organic synthesis.
Although these three halogenated hydrocarbons all contain halogen atoms, they have their own characteristics in chemical reactions and physical properties due to structural differences. Researchers of organic chemistry should analyze them in detail and make good use of them to achieve the delicacy of organic synthesis.
