Within each functional group, the boiling points of members of the group vary according to molecular weight. Therefore, one cannot deduce any functional group from boiling points.
Organic compounds are divided into families called homologous series. Each homologous series has a functional group common to all the members of the series. As a result of this, the chemical properties of all the members of the homologous series are similar.
However, the boiling points of the members of a homologous series vary according the their molecular weights. As such, boiling points can not be used as evidence to classify substances into any particular homologous series.
Summarily, one cannot deduce any functional group from physical properties.

<u>Answer: </u>The molar mass of the metal is 96.45 g/mol
<u>Explanation:</u>
The fluoride of the metal formed is 
The oxidation half-reaction follows:
Calculating the theoretical mass deposited by using Faraday's law, which is:
......(1)
where,
m = actual mass deposited = 1.25 g
M = molar mass of metal = ?
I = average current = 3.86 A
t = time period in seconds = 16.2 min = 972 s (Conversion factor: 1 min = 60 sec)
n = number of electrons exchanged = 
F = Faraday's constant = 96500 C
Putting values in equation 1, we get:
Hence, the molar mass of the metal is 96.45 g/mol
Answer:
The amount of CaCl2 produced depends on the amount of HCl in the reaction.
Explanation:
The amount of HCl is used completelyin the reaction unlike CaCO3 which remains after reaction.
