Explanation:
Answer:
To determine the number of constitutional isomers of C4H9Br, we can generate different structures by rearranging the atoms. The molecular formula C4H9Br implies a carbon chain with four carbon atoms, and one bromine atom.
Here are the constitutional isomers for C4H9Br:
1. **n-Butyl Bromide**: This is the straight-chain isomer where the bromine atom is attached to the end carbon atom.
2. **Isobutyl Bromide**: This is an isomer with a branched chain. The bromine atom is attached to one of the middle carbon atoms in the chain.
3. **sec-Butyl Bromide**: Another branched isomer where the bromine atom is attached to one of the middle carbon atoms but in a different position compared to isobutyl bromide.
4. **tert-Butyl Bromide**: This isomer has a highly branched structure where the bromine atom is attached to a carbon atom that is part of a tertiary (3°) carbon center.
two metal anions
a metal cation and a nonmetal anion
two nonmetal cations
ionic compounds are held together by ionic bonds are formed by the transfer of electrons from a metal to a non metal
Ionic bond is formed by the electrostatic attraction between the oppositely charged ions.
metals give out electrons and becomes positively charged. positively charged ions are called cations. so these are called metal cations
the electrons given out are taken in by non metals and become negatively charged. negatively charged ions are called anions. then they are called non metal anions.
so ionic compounds are formed by the electrostatic attraction between metal cations and non metal anions.
therefore ionic compounds are composed of a metal cation and a nonmetal anion

It has three nonbonding electrons.
It has five valence electrons available for bonding.
It has five nonbonding electrons.
Answer:The answer is "It has five valence electrons available for bonding". An element's group number is equivalent to the number of valence electrons that it has. This means that since phosphorus is found on group number 5, it has 5 valence electrons that participate in bonding. It also means that it needs 3 more electrons to complete its valency.
