State whether each of these statements is true or false. (a) The longer the bond, the stronger the bond. (c) A typical double bond length is in the 500–1000 pm range.

Verified step by step guidance

1. Step 1: Understand the relationship between bond length and bond strength. Generally, shorter bonds are stronger because the atoms are closer together, leading to stronger attractive forces. Therefore, evaluate the statement 'The longer the bond, the stronger the bond' based on this understanding.
2. Step 2: Consider typical bond lengths for single, double, and triple bonds. Single bonds are generally longer than double bonds, which are longer than triple bonds. This is due to the increased number of shared electrons in multiple bonds, which pulls the atoms closer together.
3. Step 3: Evaluate the statement about double bond lengths. Typical double bond lengths are usually in the range of 120–140 pm (picometers), not 500–1000 pm. Compare this with known data for common double bonds, such as C=C or C=O.
4. Step 4: Use the information from Steps 1 and 2 to determine the truth value of statement (a). Since longer bonds are generally weaker, the statement 'The longer the bond, the stronger the bond' is false.
5. Step 5: Use the information from Step 3 to determine the truth value of statement (c). Since typical double bond lengths are much shorter than 500–1000 pm, the statement is false.
