When performing an N-doping for a molecule, atoms with higher valence electron atoms are used here. Does it matter if the atoms used for the n-doping are higher in mass or lower in mass, preference wise
For example, if Silicon went through an N-doping, would it prefer Phosphorous (Mm: 30.97 g), Nitrogen (14.01g), or Arsenic (74.92 g)?
Question- Draw the structure of the product expected when D-fructose (figure below) is subjected to methylation followed by acidic hydrolysis.
The equilibrium constant for a reaction is 0.0752 at 480 degrees Celsius. Explain what is the value of the equilibrium constant for the reverse reaction occurring at the same temperature
H2s and H20 have similar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H20 is a liquid. Use bonding principals to expalin why this is.
A 0.4088 g sample of a monoproticacid neutralizes 16.4 mL of 0.08133 M KOH solution. Calculate the molar mass of the acid.
