Answer:
2-methylebutane
Explanation:
it is a hydrocarbon and there is a specific Rule for its nomenclature.
that is known as IUPAC naming system. According to it
- The compound that has all single bonds name ends on ane.
- Names according to the number of Carbons,
* For one carbon compound it is known as methane,
* For 2 ethane,
* For 3 propane
* For 4 Butane and so on.
- select the longest chain of compound
- Start numbering with lowest substituted position at carbon
- branch compound name as Iso and neo as whole
So keeping in mind the compound can be named as
2-methylebutane
- As the longest chain contain four carbon atoms so it will name as butane
- The substitution of methyl group is on C-2
*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.
Answer:
I. The balloon has a volume of 22.4L
III. The balloon contains 6.022x10^23 molecules.
Explanation:
At stp, it has been proven that 1mole of a gas occupy 22.4L.
Therefore, option (i) is correct.
The molar mass N2 = 14.01 x 2 = 28.02g/mol
Number of mole of N2 = 1 mole
Mass of N2 =..?
Mass = mole x molar Mass
Mass of N2 = 1 x 28.02 = 28.02g.
The mass content of the balloon is 28.02g, therefore, option (ii) is wrong.
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of N2 also contains 6.02x10^23 molecules
Therefore, option (iii) is correct.
The correct options to the question are:
Option i and option iii
