Answer:
Strongest intermolecular force
Hydrogen Bonding (H-Bonding)
Hydrogen bonds are caused by highly electronegative atoms. They only occur between hydrogen and oxygen, fluorine or nitrogen, and are the strongest intermolecular force.
Answer:
The correct answer is making observations in his experiment. In his cathode ray tube experiment J. J. Thomson proved that the cathode rays are indeed negatively charged particles.
Answer:
Ketone.
Explanation:
Alkynes experience additions of water catalyzed by acids, across the triple bond in the presence of <u>mercuric ion as a catalyst</u>. Generally, a mixture of mercuric sulfate and aqueous sulfuric acid is used.
Under acidic conditions, mercury is replaced by hydrogen to form a vinyl alcohol, called enol.
<u>Enoles tend to be unstable</u> and isomerize in ketones. This quick equilibrium is known as the keto-enol tautomerism.
Explanation:
In normal atmosphere, analytical reagents may absorb water molecules that may affect the results of chemical reactions. So, in order to get accurate results from these analytical regents, they must be stored in a dessicated atmosphere or heated before being used so that the water molecules must dry away.
