Which statement correctly identifies the compound that reacts the fastest, the colour of its precipitate, and the role of water in the reaction?
Compound Z reacts the fastest, forming a yellow precipitate, and water acts as a nucleophile.
Compound X reacts the fastest, forming a white precipitate, and water acts as a nucleophile.
Compound Z reacts the fastest, forming a yellow precipitate, and water acts as an electrophile.
Compound Y reacts the fastest, forming a cream precipitate, and water acts as a nucleophile.
