Question

I reached the station. I will call you (join the sentences using *when')

Answer 1

I will call you when I reach the station.

Answer 2

Correct Sentence:

When I reach the station, I will call you.

• We should never use the future tense "will" in time clauses.

• we should use the simple present tense in the 'when clause'.

• "When I reach the station, I will call you " is the correct sentence as it gives the proper meaning of the sentence.

• We should not use the word "will" after the time clauses such as "when", If, after, as soon as, etc.

• "When I reach the station" - is not the future tense because  'when' is the time it happens.

• So, "when I reach the station, I will call you " is the correct sentence.
