Answer:
A,D,E,F
Explanation:
A.Ketones generally have lower boiling points in relation to alcohols because of the intermolecular hydrogen bonds.
D.Aldehyde group is known for this C=O group in which Carbon has a double bond with Oxygen.
E. Aldehydes and Ketones can’t hydrogen bond with each other but they can hydrogen bond with water
F. Formaldehyde used in the laboratory for preservation is a liquid at room temperature while propanol which has more carbon is gaseous
B is wrong because as the Carbon increases the solubility in water decreases
C is wrong because 2-butanol has a bp of 100 degree celsius while butanal has a bp of around 74.
Answer:
AB + CD → AC +BD
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Example:
The following reaction is double replacement reaction.
CaCO₃ + 2HCl → CaCl₂ + H₂CO₃
While,
A + B → AB
Synthesis reaction:
It is synthesis reaction. The reaction in which two or more simple substance react to give one or more complex product.
AB → A + B
Decomposition:
It is the decomposition reaction. The reaction in which one reactant is break down into two or more product.
AB + C → AC + B
Single replacement:
It is the reaction in which one elements replace the other element in compound.
