The C_7 compound which gives 3 signals in the broadband proton-decoupled ^13C spectrum could be: a) Heptane
b) 2-Methylhexane
c) 3, 3-Dimethylpentane
d) 2, 4-Dimethylpentane
e) 2, 2, 3-Trimethylbutane

d) 2, 4-Dimethylpentane

Explanation:

2, 4-Dimethylpentane is the c_7 compound that gives 3 signals in the broadband proton decoupled ¹³C spectrum.

This compound is classified as an alkane and it's chemical formula is [(CH3C)2CH]2CH2. It is a hydrocarbon that has no odor. When it is combined with other gas compounds it gives high octane fuel.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
