Significant digits:
In a number, the digits which contribute to the precision of the number are said to be significant digits.
Rules for determination of significant digits in a number:
- All non-zero digits are significant.
- The zero’s appearing between two non-zero digits are significant.
- The zero’s before the non-zero numbers are not significant.
- Zero’s after non-zero number without decimal are non-significant.
- Zero’s after non-zero number with decimal are significant.
- Zero’s after the decimal point are significant.
- Any numbers with scientific notation are significant.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
