What is the molecular formula of aspirin? iii. State the technique that can be used to determine the molecular weight of aspirin b) i. Given the structure of all the isomers of a compound with molecular formula C3H6Cl2 ii. Which structure(s) in b(i) is(are) optically active?
Bond Parameters
Many factors decide the covalent bonding between atoms. Some of the bond parameters are bond angle, bond order, enthalpy, bond length, etc. These parameters decide what kind of bond will form in atoms. Hence it is crucial to understand these parameters in detail and understand how changing these parameters affects the kind of bonding or various characteristics.
Bond Dissociation Energy
The tendency of an atom to attract an electron is known as its electronegativity.
