The C-C bond length in ethane is 1.54 Angstroms and in ethene is 1.34 Angstroms. What is the numerical difference in these lengths in picometers?
Q1. The C-C bond length in ethane is 1.54 Angstroms and in ethene is 1.34 Angstroms. What is the numerical difference in these lengths in picometers?
Answer: 20
Explanation: The difference is 1.54 - 1.34 = 0.20 Angstroms. Since 1 Angstrom = 100 pm, 0.20 Angstroms equals 20 pm. 200 is a factor error.
