Given the equation: ch4 + br2 → ch3br + hbr which type of reaction does this equation represent
2 answers:
Answer : The given equation represents "Substitution reaction" of alkanes
Explanation :
The given reaction is,
To find out the type of reaction, we need to look at the reactants and products involved in the reaction
CH₄ is an alkane known as methane and Br₂ is bromine which belongs to halogen family.
During the reaction , we can see that one of the H atoms of methane is substituted by Br to form a product CH₃Br.
Therefore this is a "substitution reaction of alkanes" Since a hydrogen atom gets replaced by a halogen atom, it is also termed as "halogenation of alkanes"

<u>Answer:</u> The weak bond having slightly positive region and a slightly negative region is polar covalent bond.
<u>Explanation:</u>
Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. <u>For Example:</u> HCl, etc..
They are of two types:
- <u>Polar covalent bond:</u> This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond.
In this bond, a dipole is created. More electropnegative atom will have a slight negative charge and less electronegative atom will have a slight positive charge. For Example: etc..
- <u>Non-polar covalent bond:</u> This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example:
etc..
Hence, the weak bond having slightly positive region and a slightly negative region is polar covalent bond.
