Radiation is the transfer of heat through electromagnetic waves.
Examples include a metal spoon getting hot when placed...
- Q4. What are the three classes of organic solvent
- Ans.
The three classes of organic solvents are polar protic, polar aprotic, and nonpolar.
Polar protic solvents have hydrogen atoms bound to oxygen or nitrogen, such as water and alcohols.
Polar aprotic solvents do not have hydrogen atoms bound to oxygen or nitrogen, such as acetone and DMF.
Nonpolar solvents have no hydrogen atoms bound to oxygen or nitrogen, such as hexane and benzene.
- Q5. Define octane number
- Ans.
Octane number is a measure of a fuel's ability to resist knocking or pinging in an internal combustion engine.
Octane number indicates the quality of gasoline in terms of its resistance to knocking during combustion.
Higher octane numbers mean the fuel is more resistant to knocking, allowing for higher compression ratios in engines.
Octane number is determined through testing in a standardized engine and comparing the res...
