Answer:
isomers
Explanation:
Compounds that have the same molecular formula but different chemical structures are called isomers. Remember isomerism is a property between a pair (or more) of molecules, i.e. a molecule is an isomer of another molecule.
 
        
                    
             
        
        
        
Answer:
Via covalent bonds
Explanation:
Atoms in molecules are bonded together via covalent bonds. Covalent bonds are bonds that are formed by sharing of the valence electrons between two atoms. 
The atoms can be of the same kind or of different kinds. 
- In most molecules, the two atoms are connected by sharing of their valence electrons. 
- This way, each atom can attain stability by becoming isoelectric with the nearest noble gas. 
- Some molecules are monoatomic, some are polyatomic. 
 
        
             
        
        
        
A measure of the ability of a substance, or more generally of any physical system, to transfer heat energy to another physical system. The temperature of a substance is closely related to the average kinetic energy of its molecules.
