Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Third member of alkane is propane (C3H8)
Reason (R): It is obtained from general formula CnH2n
The correct answer for this question is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Alkanes are a class of hydrocarbons that consist only of carbon and hydrogen atoms. The general formula for alkanes is CnH2n+2, where n represents the number of carbon atoms in the molecule.
1. Alkanes:
Alkanes are a family of saturated hydrocarbons. They are called saturated because they contain only single bonds between carbon atoms. The simplest alkane is methane (CH4), followed by ethane (C2H6), and then propane (C3H8).
2. Propane (C3H8):
Propane is the third member of the alkane series, following methane and ethane. It is a colorless, odorless gas at standard temperature and pressure. Propane is commonly used as a fuel for heating, cooking, and even as a fuel for vehicles.
3. General formula for alkanes:
The general formula for alkanes is CnH2n+2. This formula represents the ratio of carbon to hydrogen atoms in an alkane molecule. For example, methane (CH4) has one carbon atom and four hydrogen atoms, ethane (C2H6) has two carbon atoms and six hydrogen atoms, and propane (C3H8) has three carbon atoms and eight hydrogen atoms.
4. Reason for Assertion (R):
The reason given in the statement is that propane is obtained from the general formula CnH2n. This is correct because when we substitute n=3 in the general formula CnH2n+2, we get C3H8, which is the molecular formula for propane.
Therefore, both the assertion (A) and the reason (R) are true, and the reason correctly explains the assertion. Propane is indeed the third member of the alkane series, and its molecular formula is derived from the general formula CnH2n.
Reason (R): It is obtained from general formula CnH2n
The correct answer for this question is option 'A' - Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
