3153
Why does Ethyl Alcohol exhibit a higher boiling point compared to Acetone?
Ethyl Alcohol shows high boiling point compared to Acetone because it forms hydrogen bonds between its molecules. These intermolecular forces require more energy to break, which is reflected in the higher boiling point. This phenomenon is a characteristic of polar molecules like Ethyl Alcohol.

3155
Which of the following intermolecular forces has the lowest strength?
Vander Waals forces are relatively weak compared to other types of intermolecular forces like hydrogen bonding and ionic interactions, and even forces among polar molecules. They arise due to temporary dipoles formed in atoms or molecules.

3157
At what distance do the attractive forces between hydrogen atoms surpass the repulsive forces?
The distance at which attractive forces between hydrogen atoms overcome repulsive forces is a specific value, representing the equilibrium bond length. This value is 75.4 pm, indicating the point where the attractive and repulsive forces are balanced.

Which of the following hydrocarbon compounds contains a carbon-carbon double bond?
Ethene (C2H4) is the simplest alkene, characterized by a carbon-carbon double bond. Acetylene contains a triple bond, while ethane and methane are saturated alkanes containing only single bonds between carbon atoms.
3160
How many atoms is each carbon atom bonded to in an ethane molecule?
In ethane (C2H6), each carbon atom is sp3 hybridized. It forms one sigma bond with the other carbon atom and three sigma bonds with three hydrogen atoms, totaling four bonds to four distinct atoms.
