Questions

Any person can have only 1 birthday i.e, the day he was born. And every year we celebrate it's anniversaries.

The stability of the ions is determined by the energy of the lone pairs. Carbon has the least effective nuclear charge (Zeff) and so the lone pair on the CH3− ion has the highest energy, making it the least stable ion and so the strongest base. The Zeff increases as we move across the period until we get to fluorine which has the greatest Zeff and so its lone pairs have the lowest energy, making F− the least basic ion.

In order of decreasing basicity they are ranked LiCH3 > LiNH2 > LiOH > LiF. We are dealing with the ions F−, OH−, NH2− and CH3− and so the factor which influences their basicity is the stability of the ion compared to its conjugate acid.

Tips

It would be wise to save this question for the interviewing manager, and not for a peer/technical discussion. Nobody likes a kiss-up, but letting management know that you will communicate openly and honestly with them, always scores big points. The last part of the question can be a good barometer about how easy it will be to become a top performer. You can follow up with a discussion of how you have been successful in your previous jobs.

Normally it takes about 22 days to become anorexic, but for some people it can be as little as 16 days or as many as 42 days.

Of course this depends a little bit on your starting weight/BMI and the health condition of the person.
