Questions & Step-by-Step Solutions
Which of the following is the general formula for alkynes?
Correct Answer: C_nH_(2n-2)
Step 1: Understand what alkynes are. Alkynes are a type of hydrocarbon that contain at least one triple bond between carbon atoms.
Step 2: Know the general formula for hydrocarbons. The general formula helps us understand how many hydrogen atoms are present based on the number of carbon atoms.
Step 3: Identify the formula for alkynes. The formula is C_nH_(2n-2), where 'C' represents carbon and 'H' represents hydrogen.
Step 4: Understand the variables in the formula. 'n' is a variable that represents the number of carbon atoms in the alkyne.
Step 5: Apply the formula. For example, if there are 3 carbon atoms (n=3), the number of hydrogen atoms would be 2(3)-2 = 4, so the compound would be C3H4.
