उत्तर : 1. "9216"
व्याख्या :

Answer: A) 9216 Explanation: It takes four of those little squares -- each one 1/2 inch on a side -- to cover one square inch. That's because each one is 1/2 x 1/2, or 1/4 of a square inch. In a rectangle that is 48 inches by 48 inches, there are 2304 square inches.(1 ft = 12 inches) Since it takes 4 little squares to cover 1 sq inch, then it would need 2304 x 4 squares (1/2 inch on a side each) to cover a rectangle 4 feet by 4 feet. That is 9,216 of those squares.

उत्तर : 1. "1, 5 – hexadiene"
व्याख्या :

Answer: A) 1, 5 – hexadiene Explanation: 3 – Hexanol: There is no alcohol stretch present in the spectrum. Therefore, the above structure is not suitable for the given spectrum.   Trans – 4 – octene: There is no vinyl bending present in the spectrum. Therefore, the above structure is not suitable for the given spectrum. 1, 5 – hexadiene: The vinyl bending and other stretches were matched with the above structure.     Hence, the c = c stretch, vinyl bending and stretch were matched with the above structure. Therefore, the given spectrum belongs to 1, 5 – hexadiene.
