The structure that corresponds to the molecule name - 4-heptanol would be option A.

<h3>Structure of 4-heptanol</h3>

The name, 4-heptanol, indicates that there are 7 carbon atoms in the structure.

In addition, there is also an indication that there is a functional group on the 4th carbon - the alcohol functional group.

Option B has only 6 carbon atoms instead of 7. Option A, on the other hand, fulfills all the criteria.

Thus, A is the correct structure of 4-heptanol.

At STP, 32 grams of O2 would occupy the same volume as:

ludmilkaskok [199]

At STP 32 g of O₂ would occupy by the same volume as 4 g of He

<h3>Further explanation</h3>

Complete question

At STP 32 g of O₂ would occupy by the same volume as:

4.0 g of He
8.0 g of CH₄
64 g of H₂
32 g of SO₂

Standard Conditions

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So the gas will have the same volume if the number of moles is the same

mol of 32 grams of O₂ :

$\tt \dfrac{32}{32}=1$

$\tt mol=\dfrac{4}{4}=1$

CH₄

$\tt mol=\dfrac{8}{16}=0.5$

H₂

$\tt mol=\dfrac{64}{2}=32$

SO₂

$\tt mol=\dfrac{32}{64}=0.5$
