    Results and Discussion: A reaction involving two bond formation was employed for the preparation of 3‚5-disubstituted 1‚2‚4-triazole as nucleobase analog. The hydrazides 2a‚b were allowed to react with the heteroaryl substituted acetonitrile derivatives 1a-c using catalytic amount of K2CO3 and n-butanol as a solvent to afford the disubstituted 1‚2‚4-triazoles 3-7 bearing benzothiazole‚ benzotriazole‚ quinoloxymethyl and benziimidazole ring systems in moderate yields.

    In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate
