Explanation:
It is known that stronger is the bonding between the atoms of a molecule more difficulty it will face to form vapors. Hence, more heat needs to be provided to the molecule. As a result, it will have high boiling point.
So, in heptanol there is hydrogen bonding. Hence, there is strong bonding so, boiling point of heptanol will be high.
On the other hand, heptane has long carbon chain as compared to pentane. Therefore, heptane will occupy more surface area and thus, more heating will be provided to it. Hence, boiling point of heptane will be greater than the boiling point of pentane.
Thus, we can conclude that rank of given compounds according to start of their boiling point is as follows.
pentane < heptane < heptanol
374u
187u
C₁₄H₂₂N₄O₈
Explanation:
To find the molecular weight of the compound C₁₄H₂₂N₄O₈ we simply sum that atomic masses of the given elements in the compound.
The empirical weight is determined by using the simplest ratio of the elements involved in the compound;
Molecular weight of C₁₄H₂₂N₄O₈;
atomic mass of C = 12g/mol
H = 1g/mol
N = 14g/mol
O = 16g/mol
Molecular weight = 14(12) + 22(1) + 4(14) + 8(16)
= 168 + 22 + 56 + 128
= 374u
Empirical weight:
Empirical formula:
C₁₄ H₂₂ N₄ O₈
14 : 22 : 4 : 8
divide by 2:
7 : 11 : 2 : 4
empirical formula C₇H₁₁N₂O₄
empirical weight = = = 187u
The molecular formula is the actual combination of atoms in a compound. so the molecular formula of the compound is C₁₄H₂₂N₄O₈
