Maximum number of isomeric monochloro derivatives which can be obtained from 2,2,5,5-tetramethylhexane by chlorination is ________
Count the types of hydrogens \((1\degree, 2\degree, 3\degree)\) to find the number of possible isomeric derivatives in halogenation.
• 2,2,5,5-tetramethylhexane has three types of hydrogen atoms:
– \(1\degree\) hydrogens (3 unique positions).
– \(2\degree\) hydrogens (1 unique position).
– \(3\degree\)hydrogens (1 unique position).
• Total number of monochloro derivatives = 3.
Two positively charged particles \(m_1\) and \(m_2\) have been accelerated across the same potential difference of 200 keV. Given mass of \(m_1 = 1 \,\text{amu}\) and \(m_2 = 4 \,\text{amu}\). The de Broglie wavelength of \(m_1\) will be \(x\) times that of \(m_2\). The value of \(x\) is _______ (nearest integer). 
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
