Which of the following hydrocarbons has a double bond in its carbon skeleton?1) C3H82) C2H63) CH44) C2H45) C2H2
Kipish [7]

Answer:

  • <u>C₂H₄</u>  (option number 4)

Explanation:

A hydrocarbon with a <em>double bond</em> in its carbon skeleton is an alkene and has the general form:

  • C_nH_{2n}.

This is, the number of hydrogen atoms is twice the number of carbon atoms.

On the other hand, alkanes have only single bonds, and the compounds with a triple bond in its carbon skeleton are alkynes.

Review each choice:

1) <u>C₃H₈:</u>

  • In this case, the number of hydrogen atoms is 2×3 + 2 = 6 + 2 = 8, which is corresponds to an alkane, not an alkene.

2)<u> C₂H₆</u>

  • For this, the number of hydrogen atoms is 2 × 2 + 2 = 4 + 2 = 6. Again an alkane, not alkene.

3) <u>CH₄</u>

  • Hydrogen atoms: 1 × 2 + 2 = 4 ⇒ an alkane

4) <u>C₂H₄ </u>

  • Hydrogen atoms: 2 × 2  = 4.  This is precisely the relation for an alkene, so this is the hydrocarbon that has a double bond in its carbon skeleton.

  • The chemical formula may be writen as CH₂ = CH₂, to show the double bond.

So, this is the correct answer.

5) <u>C₂H₂</u>

  • Hydrogen atoms: 2 × 2 - 2 = 4 - 2 = 2. This relation of carbon and hydrogen atoms corresponds to a compound with triple bond, i.e an alkyne: CH≡CH.

Look at the electron-dot diagram. What type of bond would two sulfur atoms require to form a molecule?
Blababa [14]

Answer:

Double Covalent

Explanation:

When two of the same element combine it will always be a covalent bond between them and since sulfur has two lone electrons it will make a double bond between the two to have a full octect
