A review is an argument towards your gap, not a summary of everything you read.
The most common weakness in a submitted Chapter 2 is structure. It reads as a sequence of paragraphs, each summarising one paper, in the order the author happened to read them. Nothing in it builds towards anything.
If your paragraphs begin "Sharma (2019) found…", "Then Kumar (2020) studied…", you are writing an annotated bibliography. A thematic review begins with the idea and cites the evidence for it: "Perceived organisational support has been linked to retention across sectors (Sharma, 2019; Kumar, 2020), though the effect weakens in high-attrition industries (Rao, 2021)."
Same sources. Completely different function.
Even for a narrative review, document what you did: which databases, which search strings, which date range, what you included and excluded and why. It takes one paragraph and one table, and it turns "I read some papers" into "here is my method".
A gap is not "nobody has studied this in Nagpur". That is a location, not a contribution. A defensible gap comes from one of these:
Note the last four words. Context alone is not a gap; a theoretical reason why context should change the result is.
A comparison table — study, sample, method, key finding, limitation — lets an examiner see your whole evidence base at once. A gap table maps what has been done against what has not. Between them they do more for your chapter than another two thousand words of prose.
The number itself is rarely the problem. Not being able to explain where it came from is.
Every trick you have been told about works until the day it does not, and then it is misconduct.
Scope mismatch causes more desk rejections than weak research does.
None of them are about your findings. All of them are about your decisions.
