Studdy Solution

STEP 1

Question: What does the chemical formula $\mathrm{C}_{4} \mathrm{H}_{8}$ represent?
A) A compound with 4 carbon atoms and 8 hydrogen atoms. B) A compound with 8 carbon atoms and 4 hydrogen atoms. C) A compound with 4 carbon atoms and 2 hydrogen atoms. D) A compound with 2 carbon atoms and 4 hydrogen atoms.
Answer: A) A compound with 4 carbon atoms and 8 hydrogen atoms.

STEP 2

Question: What is the general formula for alkanes?
A) $\mathrm{C}_{n} \mathrm{H}_{2n+2}$ B) $\mathrm{C}_{2n} \mathrm{H}_{n+2}$ C) $\mathrm{C}_{n} \mathrm{H}_{2n}$ D) $\mathrm{C}_{2n} \mathrm{H}_{2n+2}$
Answer: A) $\mathrm{C}_{n} \mathrm{H}_{2n+2}$

STEP 3

Question: Substituting $n=4$ into the general formula for alkanes, we get $\mathrm{H}_{2n+2}$ as which of the following?
A) $\mathrm{H}_{24+2}$ B) $\mathrm{H}_{2+24}$ C) $\mathrm{H}_{24-2}$ D) $\mathrm{H}_{4+22}$
Answer: A) $\mathrm{H}_{2*4+2}$

STEP 4

Question: Calculate the number of hydrogen atoms that would be in an alkane with 4 carbon atoms.
A) $\mathrm{H}_{8}$ B) $\mathrm{H}_{10}$ C) $\mathrm{H}_{12}$ D) $\mathrm{H}_{14}$
Answer: B) $\mathrm{H}_{10}$

STEP 5

Question: Is $\mathrm{C}_{4} \mathrm{H}_{8}$ an alkane?
A) Yes, because it has 4 carbon atoms. B) Yes, because it has 8 hydrogen atoms. C) No, because it has more hydrogen atoms than an alkane with 4 carbon atoms should have. D) No, because it has fewer hydrogen atoms than an alkane with 4 carbon atoms should have.
Answer: D) No, because it has fewer hydrogen atoms than an alkane with 4 carbon atoms should have.
