Which of the following statements about organic chemistry is correct? Be careful, there may only be one word incorrect.
Leokris [45]

In "condensed structural formula" each carbon atom and its attached hydrogen atoms are written in group in the linear form is correct about organic chemistry.

Option B

<u>Explanation</u>:

"condensed structural formula" is a method of writing or presenting organic structures in line of text. It presents all the atoms, but excludes the vertical bonds and all the horizontal single bonds. In condensed structural formula, or we can say semi-structural formula, covalent bonds are not always presented or shown. When the formula or representation is written in line with covalent bonds being shown, then it is referred to as linear formula. For example- the condensed structural formulas of ethane, propane, and ethanol is written as follows:-  

\mathrm{CH}_{3} \mathrm{CH}_{3},\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{3},\text { and } \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}

Apart from these Statement, all others are false because they do not have any logic with respect to organic chemistry.

How many total oxygen (O) atoms are present in the products side of the equation C2H5OH + 3O2 → 2CO2 + 3H2O?
kifflom [539]

Answer:

There are seven oxygen atoms in total on the product side.

Explanation:

The oxygen atom is present in both the species of CO₂ and H₂O. As there are two molecules of CO₂, so the number of oxygen atoms from it will be 4. There are three molecules of H₂O in the product side so oxygen atoms from it will be three. So, the total number of oxygen from both species is seven.
