A 32-year-old man, who was a moped, sustained facial injuries, after the assailants pulled up alongside him in Hackney at about 10.25pm (local time), BBC News reported.
They threw acid in his face then drove away after stealing his vehicle.
At 11.05pm (local time), a corrosive substance was reportedly thrown in the face of a person by two men on a moped in Shoreditch High Street.
The victim was taken to hospital, but the injuries were not believed to be life-threatening or life-changing.
At 11.18pm (local time), police received reports of a robbery in Cazenove Road, Stoke Newington, where a corrosive substance had been thrown.
Officers attended and found a man with facial injuries, who has been taken to an east London hospital with injuries that have been described as life-changing. A crime scene remains in place.
A fourth incident, in Chatsworth Road, Stoke Newington, occurred at about 11.37pm.
A man on a moped was in traffic when two men on a moped pulled up alongside him, sprayed liquid in his face, before stealing his vehicle.
The victim made his way home before calling police.
He was taken to an east London hospital and his injuries are not life-threatening or life-changing.
Following the incidents in east London, officers were made aware of a similar attack reported in Islington.
At 10.49pm (local tine), a man was reported to have had a corrosive substance thrown in his face by two men on a moped at the junction of Upper Street with Highbury Corner.

All five incidents are being treated as linked at this time, police said in a statement.
London has experienced a spate of acid attacks in recent months.
Two Australian sisters were seriously burnt in April after acid was flung into the Mangle nightclub in East London.
Isobella Fraser, 22, was in the British capital visiting her sister Prue, 20. Both experienced "painful" burns, though their faces were not touched. Up to 10 other clubbers were injured in the attack.
Last month, a young woman was celebrating her 21st birthday when a man threw acid through the open window of her car. Resham Khan suffered "life changing" burns to her face, and her cousin was hospitalised in a coma.
More to come.
