Answer #1

1)When substituent is made up of C and H only it is called as an alkyl group(substituent) e.g. in 2-Methylpropane compound (see image 1 file),-CH3 is alkyl substituent.(Option b)

  1. When substituent is made up of O and H only it is hydroxyl group e.g. in 2-Propanol compound –OH is hydroxyl substituent.(see image 2)
  2. When substituent is made of C and O only and in form of C=O then its carbonyl or Oxo group e.g.(see image 3)
  3. When substituent is made of 1 N and 2 H then its Amino –NH2 group (see image 4)

When a pipeline branches into two parallel pipes, we have seen how the flow can divide...
When a pipeline branches into two parallel pipes, we have seen how the flow can divide unevenly, depending upon the lengths and diameters of the two branches. Consider a parallel pipe system made up of two branches. For simplicity, assume that the friction factors are the same in the two branches. Pipe A has a diameter of 1.5 inches. Pipe B has a diameter of 1 inch and a length of 10 feet. So, if the pipes were the same...

Carbon, hydrogen, and oxygen are not the only elements that can be characterized by combustion analysis. If a compound also contains sulfur or nitrogen, then it will form CO​2​​ (from the carbon), H2​​O (from the hydrogen), N2​​ (from any nitrogen), and SO​2​​ (from any sulfur). The amount of oxygen in the original sample is determined from subtracting the masses of the other elements from the total, as in the combustion analysis described earlier. If a 0.500 g sample of a...

If an object is made up of only one kind of tiny particle what can we say for sure about the composition of that object? Explain. If a mixture is composed of three kinds of tiny particles, two of which are molecules and the third type is an atom, how would we describe the substances in the mixture and why? Can we mix three compounds together and end up with two new compounds and an element? If yes, how? If...
