Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The element that can form both a double bond and a single bond with a carbon atom is oxygen (O).
- Oxygen can form a double bond with carbon by sharing two electrons and a single bond by sharing one electron.
- Fluorine (F) cannot form a single bond with carbon as it requires only one electron to complete its octet and carbon requires four electrons to complete its octet.
- Therefore, fluorine can only form a single bond with carbon.
- Chlorine (Cl) and bromine (Br) can form a single bond with carbon but cannot form a double bond as they require two electrons to complete their octet and carbon requires four electrons to complete its octet.
- In addition to oxygen, nitrogen (N) can also form both a double bond and a single bond with carbon.
- However, nitrogen requires three electrons to complete its octet and carbon requires four electrons to complete its octet.
- Therefore, nitrogen can only form a triple bond or a single bond with carbon.
- It is important to note that the ability of an element to form a double or single bond with carbon depends on the number of valence electrons it has and its electronegativity.
- Fluorine (F) is the most electronegative element and can form only a single bond with carbon.
- Chlorine (Cl) and bromine (Br) have lower electronegativity than oxygen (O) and nitrogen (N) and can form a single bond with carbon.
- Oxygen (O) and nitrogen (N) are both highly electronegative elements and can form both single and double bonds with carbon.
