Question

question 5 (1 point)
how many carbon atoms are in 3 - methyl - 4,4 - diethyl - 5 - propyldecane?
a) 17
b) 19
c) 18
d) 16
e) 20

Explanation:

Step1: Analyze the parent chain

The parent chain is decane, which has 10 carbon atoms.

Step2: Analyze the substituents

• Methyl ($-CH_3$) has 1 carbon atom.
• Diethyl (2 ethyl groups, $-CH_2CH_3$ each) has $2\times2 = 4$ carbon atoms.
• Propyl ($-CH_2CH_2CH_3$) has 3 carbon atoms.

Step3: Calculate the total number of carbon atoms

Add the carbon atoms from the parent chain and substituents: $10+1 + 4+3=18$.

Answer:

C. 18
