Answer:
dipole-dipole
Explanation:
Intermolecular forces exists between the molecules of a substance in a particular state of matter.
The type of intermolecular forces present in a substance is determined by the electronegativity difference between the atoms that compose the substance.
There is a non zero electronegativity difference between Br and F hence the molecule is polar and the intermolecular forces between the molecules of BrF are dipole-dipole forces.
Answer:
Standardisation is used to determine the concentration of a volumetric solution in order to achieve accurate and reliable titration results
Phenolphthalein turn pink in basic solutions.it turn colourless in acid solution.
Hence options(1)is correct
